Why would anybody short fiat at a 5% tax? It may be that volatile in the future but that seems crazy right now. If no one shorts it how is bitusd created?
You can short against any asset, 5% may not be so unreasonable if you think USD will fall against oil/bts/btc/gold/silver. That said, I think you have a point given how much of an emphasis on currencies there is in the current root chain plan.
That is awesome.
One more question. That is 5% a year right?
Yes
Why the 5% should be hard-coded? And how can we reach the consensus that 5% is not too much?
5% may even be too little.
It would be a payoff.
What % fee is reasonable to charge someone to short a currency. (5% is rather cheap compared to the fees you would pay to other services to short order.) But here we need to get allot of people to short order so we can lend bitAssets into existence. So theres the first payoff.
Next we need to make a reasonable return for clients who want to store their money in as bitassets for the 5% return.
Here 5% may be too low. I am able to get between 4.9 and 8% annual return at my national bank's super safe, backed up, conservative money market account that doesnt require new understanding of technology or to stomach perceived risk.
That's not the right perspective to look at this, IMO. Different asset classes have different interest rates. I doubt USD money markets would give you 8% return. I also doubt any bank in the world would give you 5% interest on gold deposits, denominated in gold. Bitcoin too, should have a very low interest rate, if at all, in the free market.
Also, 5% isn't much when you put a collateral against which you're loaning money. The cheapest brokerages, for instance, let you borrow USD at less than 1% against your stock portfolio.
From a saver's perspective, this seems like a good deal. I am not so sure about this from the speculator's perspective. The open market, with all its flaws, might yield better results.
I am not sure how this could be made better though. Can interest rates themselves be floating, as in market determined by some mechanism?
